To all whom t may concern.'

Be it known that we, JACOB C. LARSEN, 'al subject of the King of Denmark, and GEORGE T. JOHNSON, a citizen of the United States, and residents of Columbus, inthe county of Franklin and State of Ohio, have invented certain new and useful Improvements in Six-Wheel-Truck Constructions for Railway-Cars; and we do hereby declare the following tobe a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertainsto make and use the same.

This invention relates to an improvement in six wheel truck construction for railway cars.

The object of theinvention is to provide a system of separate holster units which w1l1 transmit both the side and center hearing loads properly to the truck frame, and also a construction which will permit of the easy .removal and replacement of the center axle and its wheels. a c

'With these and lother oh]ects 1n view, the

invention consists in auxiliary holsters ex-4 tending transversely o the truck, a longitudinal holster at each side of the truck and supported by the transverse holsters and a main center holster supported adjacent its ends hy the longitudinal holsters.

' The invention further consists in the parts l and combination of parts as ,will be more p 'fully described and .pointed out in' the claims. f

In the accompanying drawings; Figure 1 v is a view in plan of our 1m rovement, show y ing the ends'of the truckside framers broken away; Fig. 2 is a side vlew, one half being o 4 in elevation and the other halfin section through one of the longitudinal holsters Fig. 3 is a view in section en the line 3f-3 of Fig. 1; Fi 4 is a similar view -Ion the line 4-'4 of Fig. 1; Figs. 5 and 6 are views in section of two forms of side bearings on the? longitudinal bolster, and Fig. 7 is a similar sectional view as Fig. -3, showing side bearings located on the extension of the center bolster.

The invention is applicable for use with any six wheel truck, and while wehave illustrated one form of side frame in connection with our improvement, we have done so for the purpose of illustration only, and not with the intention oflimiting our invention to such, or any other particular construction of side frame.

7 represents the truck side frames, there being two to each side with their adjacent ends overla ping, as shown in Fig. 1 for the connection therewith of the frames 8 carrying .the bearing for the center axle 9.. Each side frame 7 has a bearing for a journal of an end axle 10, and each is also provided with an opening 11 for the reception of oneA end of a transverse or auxiliary holster 12, each bolster 12 being yieldingly'supported adjacent its ends, on springs 13 seated within said openings 11. The transverse holsters 12 are located as shown, one betweenfthe front'and middle, axles, and the other between rear and middle axles, and each is provided with two openings 14, shown in Figs. 2 and 4, forthe reception of the ends of the longitudinal bolster 15,'ea'ch .of the latter being supported at its ends by the transverse holsters 12.

The main bolster 16 is, in the Vpresent instance, located over the central axle 7, and is supported at its opposite ends inopenings 20 in the two longitudinal holsters 15. Its ends have suitable faces 17 and 18 (see Fig. 3) the lower faces 18 having lugs 19,- referably integral, which interlock with t e lon# gitudinal bolster 1 5 andwhich serve to hold it against endwise displacement and also serve to lock the longitudinal bolster 15 against longitudinal displacement. this construction the weight of the center bolster and its load will be suiiicient to retain the holsters in position without any further securing devices other than the lu With 19, which lugsare also shown on the longitudinal holsters. l

While the main bolster may rest at its ends on the top surface of .the longitudinal bolster, we prefer to--mount-,it in openings p shims of varying thicknesses may. he insorted in order -to compensate for misfits due to inequalities in the castings,-and for wear on partsaifectlng` the center-bearing 10l5 height.

Again inv` high capacity trucks, the brakeA rigging constitutes a very important Velethe longitudinal holstersV may lhe cast with integral side .hearings 21, or, as shown 1n Fig. 6, with pockets 22 to lreceive removable side hearing blocks..

The main or central bolster 16 must'he designed especially for heavy loads, andv -in order to possess the'required strength it 20l must have sufficient depth at its central portion. To provide for this n withoutraising the center caring,l an

4Without introducing -features which wouldA vinterfere with the easy -removal of the mid- '25 dle axle, `)we have left the bottom of the bolr ster open as shown in Fig. 3 so as to permit of the free passage and movement of the middle axle.

To suit varyingiconditions the side bearings, instead of being secured tothe longitudinal holsters, may he located as shown in Fig. 7, inwhi'ch case the main center holster is extended beyond the longitudinal bolsters, forming short cantaliver supports for 85 theside bearings. i

might he resorted to in the relativearran'gement of parts-shownand described withoutl departing fromthe spirit and scope of .our invention. Hence we would have itunderstood that we do not wish toconine ourselves tq the exact construction and arrangement of parts 'shown and described, but
